tions, each section consisting of index and ac-` count sheets removably assembled together,"

so that anyone or more of the same can be readily withdrawn and one or more fresh ones substituted therefor, and each index-sheet bears asymbol different from the other sheets, which symbols may be and preferably are letters. These letters when used are alphabetically arranged--that is to say, the first indexsheet will bear the letter A A andthe second the letter B, and so on throughout the whole alphabet, if necessary. I say if necessary, for it is obvious that more than one book if desired, may be employed, one book having a portion of the alphabet and the other another portion of4 the alphabet. However, on account of simplicity and ease in handling I prefer to'employ' but a single volume. The index-sheets are provided with projecting tabs, each face of which isprovided with the distinguishing symbol or letter, the tabs being narrow and projecting from the sheets, so-

that the letters will show from both sides of the completed book. '(lhe account or ledger sheets of the several sections each have one or more notches in their outer edges, the notch or notches in one sheet registering with those in the other sheet,,whereby any particular sheet or page can be readily reached without the necessity of `fingering the same, as is commonly the case.

The invention is shown in one simple and convenient embodiment thereof in the`accom` panying drawings, forming a part of this specication, and in which- Figure 1 is a face view of the book with the covers removed. Fig. 2 is a similar view of the page under the' first sheet of the book. Fig. 3 is a like view of the book opened, showing the Iirst index-sheet and the first accountstruct another.

sheet turned or curled back. Fig. 4 is a perspective view of the book with the upper half of the cover up and the book partially opened.

As .-hereinbefore intimated, the improvement is of particular adaptation to ledgers or account-books, in which connection it is illustrated in the drawings.

Referring to the drawings, it will be seen that the book comprises a number of sections each denoted by 2. The'leaves or sheets of the respective sections are removably held between the covers 3. These covers 3 are of `the kind commonly present in temporary binders. The leaves or sheets have along their inner edges open-ended slotsfl, adapted to receive binding devices between the covers 3. These sheets of the book are of a kind known in this class of devices, and hence I deem it unnecessary to show the manner of temporarily securing the same in place. It will be understood that the sheets comprising the several sections 2 are removably assembled between the covers 3, so that any one or more of the sheets or pages of a section or sections can be easily Withdrawn and fresh ones introduced instead with equal facility.

Each sect-ion 2 comprises an index-sheet 7 and a plurality of account-sheets 8,which latter may be ruled in a manner similar to the well-known ledger-sheet. `The index-sheet preferably, although not necessarily, opens the respective sections, and in some cases more than one index-sheettin each case may Vbe employed. The account-sheets maybe of any desirednumber. The index-sheets have along their outer edges tabs 9,which are made quite narrow and which bear the distinguishingsymbol,which is preferably a letter. Thus the index-sheet of the first section will bear the letter A, while the second index-sheet will bear the letter B, andso on throughout the alphabet or a part` of the alphabet, and these letters appear on bothsides of the tabs, so that they can be seen from either side of the book, and the tabs, it will be seen, are out of line, by reason of which one will not ob- The index-sheets have two -vertical spaces, as 10, arranged side by side, each horizontally lined to receive the names of persons, corporations, or the like, such names being followed by numbers or their equivalents to indicate the pages upon which the accounts may be found. It will be understood that the index-sheet bearing the letter A contains the names of all individuals or firms beginning with such letter. These names upon the index-sheet are followed by numbers,to be written in by the bookkeeper or account-ant, to indicate the pages upon which the accounts may be found. The second section, comprising the accounts under the alphabet-letter B, is arranged in exactly the same way. The arrangement hereinbefore specified is particularly advantageous. When one or more accounts have become dead or outlawed, the sheet or sheets containing these can be easily removed by following the procedure hereinbefore set forth and a fresh one or fresh ones inserted therefor, while a new index-sheet to correspond with the changed conditions can be substituted for the old 011e, or, if desired, an additional index-sheet may be inserted into the book to conform to such changed conditions. This withdrawal of sheets containing dead or outlawed accounts may take place annually or at other stated intervals, and by reason of the same it is not necessary to carry over from time to time old accounts, as is ordinarily done with the eX- isting forms of ledgers.

The account-sheets of the respective sections may have one or more notches or segmental indentations 11 in their outer edges, the notch or notches of one sheet registering with the notch or notches of an adjacent sheet. In the form of the book illustrated there are two groups of these account-sheets, notched in the manner indicated. These account-sheets may be ruled like the usual ledger-sheet. The first account-sheet of each series is notched along its entire edge, while the second sheet has one less notch, the third sheet has one less notch than the second, and so on throughout the group, and the same arrangement is followed with the second groupthat is to say, each series of account.

sheets comprises two groups,.each like the other. These sheets arenumbered upon their opposite faces, the numbers being serially arranged. The numbers of the alternate pages after the rst appear above the topmost notch or indentation 11, so that such numbers may be readily viewed through a notch or registering notches. It will be understood that what might be considered as the upper page of the first sheet will bear the number l, While the opposite or under page will bear the number 2, the upper page of the second 'sheet having the number 3, and the under page the number 4, and so on throughout the group or groups of the several sections, each alternate number being seen through a notch or registering notchesthat is, the numbers seen through the notches are progressive, as 3, 5, 7, &c. The first number appearing through a notch will be 3, which is seen through the notch of the first sheet, the second number being the number 5, which is seen through the notches of the first and second sheets, &c. In this way the numbers of the sheets can be at once seen, so that a bookkeeper can immediately refer to a sheet without the necessity of fingering the pages, the size of the notches being such as to readily accommodate the thumb. The progressively arranged numbers 3, 5, 7, dac., therefore head the notches of the respective sheets, so that they appear opposite the registering notches of the preceding sheets, by means of which when the thumb is placed upon any one of these numbers and the free or front sheets lifted the sheet desired will be at once accessible in order to inspect either page thereof.

It will be obvious from the foregoing description that the improved book comprises a plurality of sections each consisting of index and account sheets,each index-sheet having a projecting tab at its free or outer end, said tabs being out of line with each other depthwise of the book and the account-sheets having one or more notches in their outer or free edges, the notch or notches in one account-sheet registering with that or those of an adjacent account-sheet and said tabs projecting outward beyond the outer edge of the book. v

It will be remembered that the several sheets have been described as detachably bound together for the purposes hereinbefore specified. Y

Having thus described the invention, what I claim is- A book comprising a plurality of sections each consisting of index and account sheets, said index-sheets having projecting tabs out of line with each other depthwise of the book, and the'account-sheets having one or more notches in their outer or free edges, the notch or notches in one account-sheet registering withthat or those of an adjacent accountsheet, said tabs projecting outward beyond the outer notched edges of said sheets and being alphabetically marked, 'and the account-sheets bearing numbers at the head of theA notches coinciding with the notch or notches of the preceding account-sheets.

. In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. v
